When adding large number of cards to inventory/deck, when you type in the card name at a certain point you end up with the needed card highlighted. Then you can press F5/F6/F7/F8 to add this card to desired collection. But after that if you start typing, it continues the previous entry. Would be nice if the text would reset after adding the card to a collection, because it is obvious that you have found the card you've searched for (since you pressed F5/F6/F7/F8) and you want to move on to the next card.

This feature will simplify adding large numbers of cards a lot.
